Patent JP-H10116988-A (JP)
Title: Semiconductor device and fabrication thereof
Inventor: YOSHIMURA HISAO
IPC: H01L29/78
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To ensure a reliable transistor operation even for a very long gate length by forming a gate electrode through a gate insulation layer on a channel region between source and drain regions and forming an insulator layer between source and channel regions and between drain and channel regions. SOLUTION: An insulation barrier layer 17 is formed between a source region 14 and a drain region 15 abutting on a channel region 11a. The insulation barrier layer 17 blocks formation of a current path in the vicinity of the deepest part in source and drain regions upon occurrence of short channel effect. Consequently, electrical conduction in the vicinity of the deepest part in source and drain regions is retarded significantly and short channel effect is suppressed. According to the arrangement, leak current of transistor is controlled without increasing the impurity concentration of channel and short channel effect is suppressed while preventing deterioration of breakdown strength thus ensuring normal transistor operation while breaking through the limit of fine patterning.

Title: Paging response system
Inventor: ABE MASAHIKO
IPC: H04M11/02
Filed: 1983-11-16
Abstract: PURPOSE:To attain plural paging calls and responses by one device at the same time by providing a temporary storage circuit storing extension numbers of plural callers and individual numbers of called parties corresponding to the extension numbers to a voice paging device. CONSTITUTION:When an extension telephone set TEL-1 dials a specific number of paging call, a central controller connects the TEL-1 to a paging device PGU so as to attain paging call. When an individual number of the called party is dialed from the TEL-1, the PGU stores temporarily the extension number and the called party number of the TEL-1 so as to await the response of the called party. Thus, the PGU stores temporarily the called party number corresponding to the plural extension numbers. When the called party dials a specific number and dials the individual number of the called party itself, the PGU selects a corresponding number out of some individual numbers so as to connect it to the corresponding extension number and eliminate the number stored temporarily.

Title: Variable volumetric fuel delivery valve assembly
Inventor: MAAKU ARAN MITSUCHIERU
IPC: F02M59/46
Filed: 1990-08-14
Abstract: PURPOSE: To optimize fuel processing characteristics and actuation of an engine by providing a variable displacement type retraction valve collar on a delivery valve, and providing this with a leak passage provided by a small flat part extended to cross only part of it. CONSTITUTION: In high speed operation of an engine 14, a valve assembly is rapidly moved from a valve seat 100 of it, fuel pressure waves move through a delivery passage 110 of a rotor 62 to a fuel supply passage, and after delivery, rapid retraction is started. During this while, for speed of a valve element 78, flat parts 116, 118 will not have discharge effect because of rapid stop, but only a very little quantity of fuel is brought by the flat parts 116, 118. In low speed operation of the engine 14, the valve element moves toward the valve seat 100 at a relatively low speed, so the flat parts 116, 118 act as fluid leak passages. Capacity of fuel retracted by a retraction collar 96 is thus smaller than that in high speed operation because of leak from around the flat parts 116, 118 into a pocket 106.
